Spain: Study shows climate change boosts olive tree-devouring bacteria in the Mediterranean

Tridge summary

Researchers from the Institute of Cross-disciplinary Physics and Complex Systems (IFISC) and the Institute of Physics of Cantabria (IFCA) have discovered that the deadly bacterium Xylella fastidiosa, which has already caused significant damage to Mediterranean crops, is likely to spread further due to climate change. The study, published in Scientific Reports, reveals that an increase in global temperature of over 3 degrees compared to pre-industrial levels could significantly increase the risk of the bacterium's establishment in wine-producing regions. The research also anticipates that the main vector of the disease, the meadow spittlebug, may decline in number, potentially expanding the bacterium's ecological niche. This finding underscores the need to mitigate the effects of climate change on agricultural systems to prevent the further spread of X. fastidiosa.

Xylella fastidiosa, the deadly disease-causing bacterium that has already wiped out millions of plants of emblematic Mediterranean crops, like grapevines, olive-trees and almond-trees, by clogging their ducts and plant tissues, will get a boost from climate change in relevant wine-producing regions where the risk is low at present.Researchers at the Institute of Cross-disciplinary Physics and Complex Systems (IFISC), a joint center of the Spanish National Research Council (CSIC) and the University of the Balearic Islands (UIB), have developed a new technique to characterize the risk of establishment of Pierce's Disease, and using state-of-the-art climatic data, have obtained predictions about the future expansion of the disease under different scenarios posed by global warming. Researchers from the Institute of Physics of Cantabria (IFCA), a joint center of the CSIC and the University of Cantabria, have collaborated in the work.These findings, published in a study in the journal ...
